Abstract
A white laminated polyester film includes a white polyester layer (B) containing fine voids, and white polyester layers (A) containing inorganic fine particles and laminated on both surfaces of the white polyester (B). The white laminated polyester film has a predetermined relationship between the elastic modulus in the longitudinal direction and transverse direction and the specific gravity, and thus has excellent whiteness, printability and crease resistance. A receiving sheet for thermal transfer recording using the white laminated polyester film as a substrate causes no trouble in paper feeding and a clear printed image during printing. The white laminated polyester film of the present invention has optimum characteristics as a receiving sheet substrate for thermal transfer recording.
